How to configure the cash rounding method¶

Use cash rounding when the total of an invoice must be a multiple of the smallest coin or banknote that customers really pay with, for example 1.00. Enable the feature in Accounting ‣ Configuration ‣ Settings, create a rule in Accounting ‣ Configuration ‣ Accounting ‣ Cash Roundings, then choose the rule in the Other Info tab of a draft invoice. Viindoo rounds the total and records the difference, either as a separate Rounding line or inside the biggest tax.

Who	An accounting administrator enables the feature (Settings). Users with the Invoicing access right create the rules and apply them to invoices.
App	Accounting

Before you start

Install the Accounting & Finance app.
Know the profit and loss accounts that will receive the rounding difference, for example 711 Other income and 811 Other expenses of the Vietnamese chart of accounts.
Cash rounding is applied to a draft invoice. See How to create a customer invoice.

How do I enable cash rounding?¶

Go to Accounting ‣ Configuration ‣ Settings.
In the Customer Invoices section, tick Cash Rounding, then click Save. The Cash Roundings menu now appears in Accounting ‣ Configuration ‣ Accounting.

How do I create a cash rounding rule?¶

Go to Accounting ‣ Configuration ‣ Accounting ‣ Cash Roundings and click New.
Fill in the rule (see the table below). For example, to round the total up to the next 1.00 by adding a line: Rounding Precision 1.00, Rounding Strategy Add a rounding line, Rounding Method Up, with a profit account and a loss account.
To put the difference in the tax instead of a separate line, choose the strategy Modify tax amount. The profit and loss accounts then disappear from the form, because the difference goes into the account of the biggest tax.

Which fields matter in the rule?¶

Field	What it affects	If left empty or wrong
Name	The name you choose on invoices. With the strategy Add a rounding line it is also the label of the rounding line.	Required.
Rounding Precision	The smallest amount that the total must be a multiple of (for example 1.00).	It must be greater than 0: Please set a strictly positive rounding value.
Rounding Strategy	Add a rounding line: Viindoo adds a Rounding line to the invoice. Modify tax amount: no line is added, Viindoo changes the biggest tax of the invoice.	Modify tax amount does nothing on an invoice without tax.
Profit Account	The account that receives the difference when the rounding increases what the customer pays. Shown, and required, only for Add a rounding line.	Empty: the field stays red and you cannot save the rule.
Loss Account	The account that receives the difference when the rounding decreases what the customer pays. Shown, and required, only for Add a rounding line.	Empty: the field stays red and you cannot save the rule.
Rounding Method	How the total is rounded to the precision (see below).	Required.

Rounding Method	Rule	Total of 425.90 with a precision of 1.00
Up	Always rounds up to the next multiple of the precision.	426.00
Down	Always rounds down to the previous multiple.	425.00
Nearest	Rounds to the closest multiple: up when the remainder is half of the precision or more, otherwise down.	426.00

How do I apply a cash rounding rule to an invoice?¶

Open a draft invoice (or create one in Accounting ‣ Customers ‣ Invoices).
Open the Other Info tab and choose the rule in Cash Rounding Method.
Click Confirm. The invoice keeps the rounded total.

What does an invoice look like with each strategy?¶

The two examples below use the same invoice: 3 units at 123.45 with a 15% tax, and a rule that rounds up to 1.00. Before rounding, the untaxed amount is 370.35 and the tax is 55.55, so the invoice is 425.90.

Add a rounding line¶

The totals block shows a Rounding line of 0.10 and a Total of 426.00. The line is recorded in the profit account of the rule.

Invoice totals with a Rounding line of 0.10

Modify the tax amount¶

There is no Rounding line: the tax of the invoice becomes 55.65 and the Total is 426.00.

Invoice totals where the tax amount absorbs the rounding

Note

Rounding down is also possible: with the method Down, the same 425.90 becomes 425.00 and the difference of 0.90 is recorded in the loss account.

Expected result¶

The total of the invoice is a multiple of the rounding precision.
With Add a rounding line, the journal entry has one more line, in the profit account (rounding up) or the loss account (rounding down). With Modify tax amount, the tax line itself changes.

Common errors¶

Message or symptom	What to do
Please set a strictly positive rounding value.	Enter a Rounding Precision greater than 0.
The Profit Account or the Loss Account is red and the rule is not saved.	Fill in both accounts, or choose the strategy Modify tax amount, which needs none.
The Cash Roundings menu does not appear.	An accounting administrator must tick Cash Rounding in Accounting ‣ Configuration ‣ Settings.
